How
<http://earth2tech.com/2009/08/19/how-data-centers-can-follow-energy-prices-
to-save-millions/> Data Centers Can Follow Energy Prices to Save Millions
Companies that own numerous data center operators across the globe could be
able to save millions of dollars a year in electricity costs if they
dynamically shifted computing power across their data centers to when and
where energy prices are the cheapest. At least that's according to a study
out this week from the Massachusetts Institute of Technology and Carnegie
Mellon (hat
<http://arstechnica.com/business/news/2009/08/saving-money-by-load-balancing
-to-where-electricity-is-cheap.ars> tip Ars Technica).
In other words, companies that have lots of data centers can take advantage
of cheap bandwidth, smart software and fluctuating hourly energy prices to
shift computing power to a data center in a location where it's an off-peak
time of the day and energy prices are low. Commonly that's in the middle of
the night, which is why industry-watchers like Rich
<http://www.datacenterknowledge.com/archives/2009/07/15/googles-chiller-less
-data-center/> Miller, editor of Data Center Knowledge, call the process
"following-the-moon."
For data centers that are more "energy proportional" - using energy
efficiently across a range of activity levels, from idle to peak load, as I
<http://pro.gigaom.com/2009/06/google-servers-should-be-more-like-people/>
explained on GigaOM Pro (subscription required) - and don't have any
constraint on bandwidth use and speed, the savings could be as high as 13-30
percent.
The study is interesting because while some companies with massive
distributed data centers are starting to employ these tactics (data center
software maker <http://www.cassatt.com/prod_enterprise.htm> Cassatt, for
example, sells a product that dynamically shifts loads to find the cheapest
energy prices), this is still a relatively new concept. It's particularly
interesting for companies that offer cloud computing services, selling
scalable on-demand computing as a service, since they could use their
massive networks to create significant savings and pass that onto their
customers.
Given many cloud computing providers are already shifting computing loads to
different locations to provide fast delivery and on-demand bandwidth, the
researchers suggest that adding in an energy price cost policy wouldn't be
that difficult. And
<http://earth2tech.com/2009/08/17/how-digital-music-can-fight-climate-change
/> as longtime IT energy researcher Jonathan Koomey found in one of three
reports released this week, cloud computing companies are already leading
the charge in being smarter about energy use.
An alternative, which
<http://earth2tech.com/2008/07/25/data-centers-will-follow-the-sun-and-chase
-the-wind/> Stacey on GigaOM has written about, is helping data centers
shift computing loads to tap into renewable power. But unfortunately for the
time being, until clean power drops in price, that's not going to save you a
whole lot of money.
